      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Treatment, Randomization description: Random method: Simple random
Random double blind
Referral by a neurologist
120 envelopes: 40 pieces A (treatment), 40 pieces B (placebo), 40 pieces C (gabapentin) sealed and closed, in front of the secretary. Upon arrival, each patient is given a random envelope. The secretary only provides packages containing materials A, B and C to patients and does not know their contents, Blinding description: In this study, only the principal investigator and outcome assessor are aware of the contents of the envelope. Patients and others involved in the design have no information about the type of material in the envelopes. Drug and placebo are similar in shape, color, odor, packaging, and appearance, and blinding has been performed between them. Gabapentin capsule group is the standard treatment.</study_design>
